Key Findings in This Report

• Optimal FSW parameters (1200 rpm, 60 mm/min, 2° tilt) achieve 82% joint efficiency for dissimilar AA6061-T6/AA7075-T6. • Rotational speed and welding speed are the most significant parameters affecting tensile strength and hardness. • RSM-based models accurately predict mechanical properties, reducing experimental trials by 40%. • Fine equiaxed grains in the nugget zone enhance joint strength and ductility.
